Good idea! I hadn't thought of that... use CP as an offsite backup facility. Hmmm. I wonder if the hamsters will complain...
Real men don't use instructions. They are only the manufacturers opinion on how to put the thing together.

Do you have a point?
That looks like at least a few dozens of function points to me.
Agh! Reality! My Archnemesis![^]

makumazan84, when PIEBALDconsult talked about blood, I thought that exact scene you described. Kill Bill is a masterpiece ... and the code, of a very particular way, it is also. As you get dizzy, I think in Visual Studio that could be solved with several sections #region. :cool:

:sigh: This sort of horror is quite normal, but seldom are we given an example that we DON'T have to read...and thank you, those who did so! :laugh:

hmmm...in VS2003 and in VS2008SP1, you can't define #regions within a function body

Yeah, I had the same reaction the first time I wanted to use it, some time about two years ago. I dislike large function bodies, but realistically there are a number of situation-specific algorithms that depend on a long sequence of unrepeated operations. To reduce the size, one is left with the option of breaking them into smaller chunks as subroutines, then calling each subroutine in sequence. I've seen differences in how well that approach works when maintenance is being performed by novices to the software. I've seen genuinely intense frustration expressed by some developers when they have to nest down through two or more levels of subroutine that were simply put in to eliminate very lengthy code sequences, where the developer in question felt it would have been much easier to follow the sequence in its original lengthy form. Allowing collapsible regions within a subroutine brings the best of both techniques to bear on the problem.
